What then do we commonly regard as valid ultimate reasons for acting or abstaining? This, as was said, is the starting-point for the discussions of the present treatise: which is not primarily concerned with proving or disproving the validity of any such reasons, but rather with the critical exposition of the different ‘methods’—or rational procedures for determining right conduct in any particular case—which are logically connected with the different ultimate reasons widely accepted. In the first chapter we found that such reasons were supplied by the notions of Happiness and Excellence or Perfection (including Virtue or Moral Perfection as a prominent element), regarded as ultimate ends, and Duty as prescribed by unconditional rules. This threefold difference in the conception of the ultimate reason for conduct corresponds to what seem the most fundamental distinctions that we apply to human existence; the distinction between the conscious being and the stream of conscious experience, and the distinction (within this latter) of Action and Feeling. For Perfection is put forward as the ideal goal of the development of a human being, considered as a permanent entity; while by Duty, we mean the kind of Action that we think ought to be done; and similarly by Happiness or Pleasure we mean an ultimately desired or desirable kind of Feeling. It may seem, however, that these notions by no means exhaust the list of reasons which are widely accepted as ultimate grounds of action. Many religious persons think that the highest reason for doing anything is that it is God’s Will: while to others ‘Self-realisation’ or ‘Self-development,’ and to others, again, ‘Life according to nature’ appear the really ultimate ends. And it is not hard to understand why conceptions such as these are regarded as supplying deeper and more completely satisfying answers to the fundamental question of Ethics, than those before named: since they do not merely represent ‘what ought to be,’ as such; they represent it in an apparently simple relation to what actually is. God, Nature, Self, are the fundamental facts of existence; the knowledge of what will accomplish God’s Will, what is, ‘according to Nature,’ what will realise the true Self in each of us, would seem to solve the deepest problems of Metaphysics as well as of Ethics. But just because these notions combine the ideal with the actual, their proper sphere belongs not to Ethics as I define it, but to Philosophy—the central and supreme study which is concerned with the relations of all objects of knowledge. The introduction of these notions into Ethics is liable to bring with it a fundamental confusion between “what is” and “what ought to be,” destructive of all clearness in ethical reasoning: and if this confusion is avoided, the strictly ethical import of such notions, when made explicit, appears always to lead us to one or other of the methods previously distinguished.
There is least danger of confusion in the case of the theological conception of ‘God’s Will’; since here the connexion between ‘what is’ and ‘what ought to be’ is perfectly clear and explicit. The content of God’s Will we conceive as presently existing, in idea: its actualisation is the end to be aimed at. There is indeed a difficulty in understanding how God’s Will can fail to be realised, whether we do right or wrong: or how, if it cannot fail to be realised in either case, its realisation can give the ultimate motive for doing right. But this difficulty it belongs to Theology rather than Ethics to solve. The practical question is, assuming that God wills in a special sense what we ought to do, how we are to ascertain this in any particular case. This must be either by Revelation or by Reason, or by both combined. If an external Revelation is proposed as the standard, we are obviously carried beyond the range of our study; on the other hand, when we try to ascertain by reason the Divine Will, the conception seems to present itself as a common form under which a religious mind is disposed to regard whatever method of determining conduct it apprehends to be rational; since we cannot know any act to be in accordance with the Divine Will, which we do not also, by the same exercise of thought, know to be dictated by reason. Thus, commonly, it is either assumed that God desires the Happiness of men, in which case our efforts should be concentrated on its production: or that He desires their Perfection, and that that should be our end: or that whatever His end may be (into which perhaps we have no right to inquire) His Laws are immediately cognisable, being in fact the first principles of Intuitional Morality. Or perhaps it is explained that God’s Will is to be learnt by examining our own constitution or that of the world we are in: so that ‘Conformity to God’s Will’ seems to resolve itself into ‘Self-realisation,’ or ‘Life according to nature.’ In any case, this conception, however important it may be in supplying new motives for doing what we believe to be right, does not—apart from Revelation—suggest any special criterion of rightness.
§ 2. Let us pass to consider the notions ‘Nature,’ ‘Natural,’ ‘Conformity to Nature.’ I assume—in order to obtain a principle distinct from ‘Self-realisation,’[72]—that the ‘Nature’ to which we are to conform is not each one’s own individual nature, but human nature generally, considered either apart from or in relation to its environment: that we are to find the standard of right conduct in a certain type of human existence which we can somehow abstract from observation of actual human life. Now in a certain sense every rational man must, of course, “conform to nature”; that is, in aiming at any ends, he must adapt his efforts to the particular conditions of his existence, physical and psychical. But if he is to go beyond this, and conform to ‘Nature’ in the adoption of an ultimate end or paramount standard of right conduct, it must be on the basis—if not of strictly Theological assumptions, at any rate—of the more or less definite recognition of Design exhibited in the empirically known world. If we find no design in nature, if the complex processes of the world known to us through experience are conceived as an aimless though orderly drift of change, the knowledge of these processes and their laws may indeed limit the aims of rational beings, but I cannot conceive how it can determine the ends of their action, or be a source of unconditional rules of duty. And in fact those who use ‘natural’ as an ethical notion do commonly suppose that by contemplating the actual play of human impulses, or the physical constitution of man, or his social relations, we may find principles for determining positively and completely the kind of life he was designed to live. I think, however, that every attempt thus to derive ‘what ought to be’ from ‘what is’ palpably fails, the moment it is freed from fundamental confusions of thought. For instance, suppose we seek practical guidance in the conception of human nature regarded as a system of impulses and dispositions, we must obviously give a special precision to the meaning of “natural”; since in a sense, as Butler observes, any impulse is natural, but it is manifestly idle to bid us follow Nature in this sense: for the question of duty is never raised except when we are conscious of a conflict of impulses, and wish to know which to follow. Nor does it help us to say that the supremacy of Reason is Natural, as we have started by assuming that what Reason prescribes is conformity to Nature, and thus our line of thought would become circular: the Nature that we are to follow must be distinguished from our Practical Reason, if it is to become a guide to it. How then are we to distinguish ‘natural impulses’—in the sense in which they are to guide rational choice—from the unnatural? Those who have occupied themselves with this distinction seem generally to have interpreted the Natural to mean either the common as opposed to the rare and exceptional, or the original as opposed to what is later in development; or, negatively, what is not the effect of human volition. But I have never seen any ground for assuming broadly that Nature abhors the exceptional, or prefers the earlier in time to the later; and when we take a retrospective view of the history of the human race, we find that some impulses which all admire, such as the love of knowledge and enthusiastic philanthropy, are both rarer and later in their appearance than others which all judge to be lower. Again, it is obviously unwarrantable to eschew as unnatural and opposed to the Divine design all such impulses as have been produced in us by the institutions of society, or our use of human arrangements and contrivances, or that result in any way from the deliberate action of our fellow-men: for this were arbitrarily to exclude society and human action from the scope of Nature’s purposes. And besides it is clear that many impulses so generated appear to be either moral or auxiliary to morality and in other ways beneficial: and though others no doubt are pernicious and misleading, it seems that we can only distinguish these latter from the former by taking note of their effects, and not by any precision that reflection can give to the
